The Grail is an item similar to an artifact in the sense that heroes can carry it and exchange it between them in the same way as artifacts. Also it can be sold for 1 unit of any resource. In fact, the Grail is sometimes unofficially referred to as the ultimate artifact. The Grail is typically hidden somewhere in the ground of adventure map, and finding it requires digging it with a hero. Recovering the Grail artifact and taking it to any town enables the player to build town specific Grail Building.
The primary bonuses of Grail Building for all towns are extra 5000 generation per day and 50% additional creature growth per week (rounded down). The growth bonus applies after all the modifiers: external dwellings and Statue of Legion or its components. Additionally, every town has its own unique bonuses.
Finding the Grail
In order to recover the Grail, a hero must dig it out of the ground. A hero without empty slots in a backpack cannot dig. Digging demands the whole amount of a hero's movement points so it is impossible to dig at the same day when a hero crossed even just one tile on the map without tinkering with fast/slow units in the hero's army. Only one Grail may be hidden in the adventure map. However, it is also possible for a mapmaker to set any number of heroes and towns to carry the Grail in their backpack or have their Grail structure built, respectively. When the Grail is buried into the ground, clues to its location can be found at obelisks. Every visited obelisk reveals a part of the puzzle map, which shows the location of the Grail marked with X. Typically the X becomes visible when the entire puzzle map is revealed, but occasionally it will be shown before the last obelisk is visited. However, it is often possible to guess roughly the area where the Grail might lie, and systematically start digging it. In fact, the AI at hard difficulty levels starts digging the Grail even if only a third of the puzzle map is completed.
If the map has no obelisks, it is completely impossible to find the grail (even if every single block on the map is dug on). Also, using "nwcoracle", a cheat that reveals the puzzle map, will have no effect and the puzzle will not show anything.
Grail Buildings and their special bonuses
When the Grail is taken to a town and the visiting hero with the Grail "visits" the Town Hall (Village Hall/Town Hall/City Hall/Capitol), a town-specific Grail Building will be built. It can be the second town building per turn, but nothing can be built on the same day after it. Also, Grail can be built in an allied town, which can be helpful if you don't have your own Tower or Conflux. All unique Grail building features will be effective for allies (except Castle, Rampart and Necropolis buildings).
